^ Yes, but there's a roughly 40m / 130 ft crown to it.
I think roof height is more relevant here and the top floor will be exactly 200m / 656 ft above the ground.
There's a somewhat annoying reason for it.
According to local regulations, safety standards are not the same when a top floor exceeds 200m.
In such a case, they go more requiring and definitely more costly.
La Défense not being the real prime location of the metro area, so far developers or businesses renting their buildings have seen no interest in surpassing the threshold enforced by the French regulator.
Everyone just wants to optimize their profits.
So you get 50 floors for 200m, that's an average ceiling height of roughly 4m (13 feet) per floor, which is ok.
The tower is developed by
TotalEnergies for their employees. Given the spot, they will enjoy exclusive views over the inner city until more towers are built around that one.
